The remote host is running PHProxy, a web HTTP proxy written in PHP.
 
There is a bug in the remote version software which makes it vulnerable to 
HTML and JavaScript injection.

An attacker may use this bug to preform web cache poisoning, xss attack, etc.

Solution : Upgrade to the newest version of this software
